Direct and Inverse Proportion
Answer:
1) The fuel consumption of a car is 5 liters of diesel per 85 kilometers. What distance can the car cover with 7 liters? - DP
2) It takes 7 days for 25 laborers to harvest mango in the orchard. How long will 35 laborers take to harvest mango on the same orchard? - IP
3) If 20 men can plant rice in a field in 10 days; in how many days can 30 men plant rice in the same days? - IP
4) The cost of transporting 30 sacks of rice for 115 kilometers in a truck is P1 500.00. What will be the cost of transporting 35 sacks for 125 kilometers? - DP
Step-by-step explanation:
Some quantities changes as another quantity changes also. For instance, when one quantity increases, the other quantity increases, or when one quantity decreases, the other quantity decreases also. This relationship is known as direct proportion. An example of this is fuel consumption increases as distance traveled increases. Another type of relationship is the inverse proportion. In this relationship, when one quantity increases, the other quantity decreases, and vice versa. An example of this is when the number of workers is increased, the time to finish the workload decreases.
